Abstract
The utility model discloses a front axle assembly for a light cross-country car, comprising a caliper disk brake, a universal joint with ball and socket, a combined type drive axle casing, a steering knuckle and a main pin. The utility model is characterized in that the caliper disk brake is connected and fixed with the steering knuckle by screws, and the main pin of the steering knuckle is positioned on both ends of the front axle assembly. The outer rings for circular cone roller bearings are pressed in the main pin holes of the sphere-shaped supports of left and right semi-axle casing tubes by adopting interference fit. The main pin of the steering knuckle, the steering knuckle and a bearing are assembled into integration to form the main pin of the steering knuckle matched with rolling friction.
Description
The utility model relates to the technology of automobile component aspect, belongs to the motor turning drive axle.
At present, no matter military the and civilian light off-road vehicle of China is basical traditional model, and still various modification of vehicle mostly are the fifties end design-calculated BJ212 type series old product, and its steering drive axle all adopts drum brake mechanism, and brake efficiency is low, and noise is big.Steering swivel adopts cliding friction to cooperate with stub, and stub is frayed serious in the use, and the wheel flutter self-aligning is relatively poor, the incompatible now requirement to cross country car of the existence of above-mentioned shortcoming.
The purpose of this utility model designs a kind of deceleration and stopping performance height, turns to stable steering drive axle flexibly, thereby reaches good reliability, and manoeuvrable is effect easily.
The purpose of this utility model can be achieved by the following scheme:
A kind of front axle assy that is used for light off-road vehicle comprises caliper brake, Rzeppa joint, steering yoke bolt.The two ends that caliper brake is positioned at front axle assy are linked together with two screws and steering swivel, and steering yoke bolt is positioned at the two ends and the steering swivel spherical bearing of front axle assy, and the ring assembling together in the taper roller bearing of garden.Described Rzeppa joint is installed in left half axle sleeve pipe and the right axle shaft sleeve pipe, and steel ball is fixedly mounted in the arc orbit of inner race and spherical shell by the ball cage.
Advantage of the present utility model:
Driven nature is good, uses to have interchangeability, and is easy and simple to handle, rational in infrastructure.
(embodiment) describes structure of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the integral structure figure of the utility model product.
Fig. 2 be among Fig. 1 caliper brake K to view.
Fig. 3 is a Rzeppa joint structure for amplifying scheme drawing among Fig. 1.
Fig. 4 is a caliper brake structure for amplifying scheme drawing among Fig. 2.
Fig. 5 is the right elevation of Fig. 4 caliper brake.
Fig. 6 is the birds-eye view of Fig. 4 caliper brake.
The keystone configuration signal is described below:
The front axle assy design has caliper brake, be positioned at the front axle assy both sides, bolt with 2 M12 connects with steering swivel (2), and steering yoke bolt (4) is positioned at the front axle assy both sides, connects one with ring (5) in steering swivel (2), spherical bearing (8), the tapered roller bearing.Rzeppa joint (12) lays respectively in the steering swivel (2) and left half axle sleeve pipe (9) and right axle shaft sleeve pipe 10 at automobile front axle assembly two ends.
6 arc orbits are arranged in the spherical shell (14), spherical shell (14) departs from the universal-joint center O symmetrically with its center of circle of decentraction that the arc orbit of inner race is done, the transversal surface of track is the line and the omnibearing line angle at 45 of crossing the centre of sphere of the oval contact point centre of sphere, oval 1.01-1.05 times of electing steel ball (18) radius at the radius of curvature of contact point as, inner race (15) is by jump ring (20), back-up ring (10) is installed on the imput shaft (17), and power transmission steel ball (18) is fixed by ball cage (16) and is installed in the arc orbit of inner race (15) and spherical shell (14).
Because Weiss universal joint needs certain predetermincd tension when assembling, could protect the characteristic of isogonism speed transmission, so vehicle steering is heavier when turning to.And Rzeppa joint the time need not apply predetermincd tension in assembling, so that it turns to is light flexibly.
Caliper brake (13) is made up of caliper brake support (22), jaw type brake cylinder casing (24), seal ring (25), piston (23), slipper (21), guide pillar (27) and screw (26), caliper brake support (22) is connected with screw (26) by guide pillar (27) with caliper brake cylinder body (24), and caliper brake support (22) adopts free-running fit assembling one with guide pillar (27).
Caliper brake principle of the present utility model is achieved in that
When automobile brake, step on automobile brake pedal, braking liquid in the automobile brake master cylinder enters caliper brake cylinder body (24) through the drg oil pipe, the braking liquid that has certain pressure promotes motion stops (23), piston (23) then promotes to press against brake disc (1) with the slipper (21) of its homonymy, the slipper (21) that antagonistic force then promotes caliper brake cylinder body (24) drive opposite side presses against brake disc (1), equate up to the both sides brake-shoe pressure, till brake disc firmly clamped, realize the purpose of braking.When stopping glancing impact, because the elasticity of seal ring (25) makes piston (23) return, slipper take-off the brake dish (1).The gap of brake disc and its both sides slipper is controlled between the 0.15-0.25 millimeter by seal ring (25), and when slipper (21) when in use wearing and tearing, the abrasion loss of its both sides slipper (21) is all compensated by piston (23).
