Embodiment Construction

[0039] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0040] see figure 1 , a vehicle front axle assembly with a toe adjustment mechanism includes a front axle 7 and a pair of wheels 1, and also includes a toe adjustment mechanism. The toe value adjustment mechanism includes a pair of adjustment mechanisms and a straight pull rod mechanism.

[0041] see figure 1 with figure 2 , a pair of adjustment mechanisms have the same structure. The adjustment mechanism includes a motor 10, a transmission rod 9 and a gear 5; the motor 10 is a stepping motor. One end of the transmission rod 9 is connected to the output shaft of the motor 10 through an electromagnetic clutch 18; the other end of the transmission rod 9 is connected to the axle of the gear 5 through a universal joint.

[0042] The straight rod mechanism includes a spline shaft 6 and a pair of straight rods 3 . Two ends of the spline shaft 6...

Abstract

The invention relates to a vehicle front axle assembly with a toe-in value adjusting mechanism, and belongs to the technical field of vehicles. The vehicle front axle assembly comprises a front axle, a pair of wheels and the toe-in value adjusting mechanism, and the toe-in value adjusting mechanism comprises a pair of adjusting mechanisms and a straight pull rod mechanism; the structures of the pair of adjusting mechanisms are the same; each adjusting mechanism comprises a motor, a transmission rod and a gear; the straight pull rod mechanism comprises a spline shaft and a pair of straight pull rods; racks are respectively arranged at two ends of the spline shaft; the straight pull rods are hollow pipes, the two ends of the spline shaft are located in ends of the corresponding straight pull rods respectively, and the other ends of the pair of straight pull rods are fixedly connected with the two ends of the front axle through a vehicle front axle respectively. And the two gears on the pair of adjusting mechanisms are respectively meshed with the racks at the two ends of the spline shaft. According to the vehicle front axle assembly, the toe-in value is dynamically adjusted in the running process of the vehicle, and the adjustment is accurate; and the problem of abnormal wear of the steering wheel caused by mismatching of toe-in and camber is solved.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a vehicle front axle assembly with a toe-in adjustment mechanism. Background technique [0002] The so-called toe angle means that when the car is stationary, any theoretical rotation plane of the two steering wheels has an included angle in the forward direction of the car. The toe-in value of the vehicle is one of the four wheel alignment parameters. During the driving process of the vehicle, the wheel camber will cause abnormal wear of the wheel. The toe-in value is used to match the camber angle to ensure that the car rolls in a straight line and avoid abnormal tire wear. During the driving process of the car, due to many factors such as changes in road conditions, load changes, and tire pressure changes, the matching relationship between the initial front wheel toe value and the camber angle will be broken. Due to the destruction of the matching relationship, t...
