Roadlouse drive front axle

Abstract

A front drive bridge of a roadlouse relates to the front bridge structure of an automobile, which is characterized in that a steering knuckle is in U-shaped structure; two U-shaped openings of two U-shaped brackets are sheathed together by the dynamic matching of pin rolls; the bottom part of the internal U-shaped bracket is fixed on the flange of a bridge shell; the bottom part of the external U-shaped bracket is fixed on the shell of an external semi-shaft; a braking mechanism is a dish braking mechanism; the U-shaped supporting seat of the dish braking mechanism is fixed on the shell of the external semi-shaft; the disk of the disk braking mechanism is fixed on the rotating hub seat of the external semi-shaft. The front drive bridge has the advantages that the U-shaped steering knuckle and the disk braking mechanism are simultaneously used in the front drive bridge of the roadlouse; when the two are matched to be used in the front bridge to steer, the braking speed is greatly quickened; braking force is also increased; the operation is flexible and the security is better. While the use of the U-shaped steering knuckle leads the mounting of a three-pin universal joint to be possible. The three-pin universal joint has the characteristics of small size, large transfer torque and constant speed drive. The front drive bridge has the advantages of flexible steering, fast braking speed, large braking force and large transfer moment to improve the comprehensive property of the roadlouse.

Description

Technical field: [0001] The invention relates to an automobile front axle structure, in particular to a small tonnage automobile driving front axle. Background technique: [0002] At present, the front axle structure of an automobile is composed of a differential transmission assembly, an axle housing, an axle housing flange, a half-shaft spherical steering knuckle, an outer half shaft of a universal joint, a wheel hub, and a steering tie rod mechanism. [0003] The steering knuckle of the front axle of a small-tonnage vehicle generally adopts a spherical knuckle structure, and the brake structure generally uses an expanding ring brake structure, such as the front axle of a Jeep. [0004] When the car is turning, it is more dangerous than when it is not turning, because if the steering is not flexible, or because pedestrians suddenly enter the dangerous line of sight when turning, it is more dangerous than not turning. With the spherical steering knuckle structure, the load...

AI Technical Summary

Problems solved by technology

In terms of its structural characteristics, the spherical structure not only has a large contact surface of the ball, but also is easy to drop the marbles and is not easy to maintain. At the same time, the spherical structure limits the space inside the ball. The general single universal joint is used, and the single universal joint is not constant velocity.
