Anonymous users2024-02-16The thrust angle is the angle between the longitudinal axis of the vehicle and the thrust line (which is an imaginary line extending from the center of the rear axle forward, and the rear axle driving direction line determined by the two rear wheels) in the overhead plane. The deflection of the thrust line relative to the longitudinal axis to the left is positive, and the deviation to the right is negative.
The thrust angle should be close to 0, which can be used as a standard basis for referring to the specifications of the car manufacturer, when the rear wheels are individually toe-in.
When adjusting, the thrust angle is adjusted at the same time.

Anonymous users2024-02-15The angle between the angle bisector of the extension line of the rolling direction of the two rear wheels of the automobile and the center axis of the vehicle.
The thrust angle is the angle formed between the geometric centerline of the car and the pointing of the rear wheels. If the rear wheels are pointing straight ahead and the axial thrust line is the same as the car's geometric centerline, the thrust angle is zero. When the car is traveling in a straight line, the rear-wheel drive car follows the thrust line, so a zero thrust angle is ideal.
The thrust angle should be adjusted at the same time as the rear wheel toe-in adjustment, but the rear suspension design may not allow the thrust angle to be adjusted according to the change in the rear-wheel toe-in.
If the thrust angle cannot be adjusted, it is better to position the thrust line than to have the front wheels aligned according to the car's geometric centerline. If the front wheels are aligned with the car's geometric centerline, and the rear wheels are driven along a thrust line that is not parallel to the geometric centerline, there will be steering wheel twisting, front-wheel camber and toe-in incorrectness during driving, tire acceleration wear or mistracking, etc.

Anonymous users2024-02-14The vehicle propulsion angle is the angle between the propulsion line and the geometric centerline, which is called the propulsion angle.
Left lateral offset: The angle between the line between the center of the left front and rear wheels and the advance line is called the left lateral offset angle. When the left rear wheel is more outward than the left front wheel, the left lateral offset is specified as a positive value in this state, and conversely, when the left front wheel is more outward than the left rear wheel, the left lateral offset is specified as a negative value in this state.

Anonymous users2024-02-12The direction of the vehicle is the vehicle advance line!
When measuring the rear wheel unilateral toe-in, it is measured with reference to the vehicle centerline (geometric centerline), and the center of the rear wheel is intersected by the bisector point of the rear wheel unilateral toe-in to determine the propulsion line, and the angle between the propulsion line and the geometric centerline of the vehicle is called the propulsion angle.
Hope it helps, hopefully!!
The car is a trackless vehicle that can drive itself, formerly known as an automatic car, because it is mostly equipped with a gasoline engine, so it is referred to as a car, which is still used today. The car is composed of an engine, a chassis and a body, and the engine emits power and drives the wheels through the transmission mechanism. >>>More
Hello! Automobile cylinder pulling" - the so-called "cylinder" refers to the cylinder inner wall is drawn into a deep groove, the piston, piston ring and cylinder wall friction pair lose tightness, resulting in the cylinder compression pressure reduction, power loss; The downward channeling of the combustible mixture increases the pressure of the crankcase, which will cause the crankcase ** in serious cases; The lubricating oil is channeled into the cylinder, causing the phenomenon of burning oil; Smoke from the exhaust pipe is severe; Abnormal engine noise; The engine does not work properly or even stalls. >>>More

Please enter your answer. According to Article 43 of the Road Traffic Management Regulations, vehicles passing through intersections without traffic signals or traffic signs must comply with the following provisions to yield in turn: (1) Feeder road vehicles give way to trunk road vehicles; (2) If there is no distinction between branch and trunk roads, non-motorized vehicles shall give way to motor vehicles, non-buses and trams shall give way to buses and trams, and similar vehicles shall give way to vehicles that go straight or there is no oncoming car on the right; (3) When similar vehicles meet in opposite directions, the car turning left gives way to the car going straight or turning right; (4) Vehicles entering the roundabout give way to vehicles already in the intersection.
