Abstract
The utility model discloses wheel side speed reduction tandem axles, which comprise wheel side speed reducers, wheel hubs, braking air chambers and disc type brakes, wherein the disc type brakes comprise braking forceps and braking discs; the first side of each wheel hub is connected with each wheel side speed reducer; the second side of each wheel hub is connected with each braking disc; and the braking air chambers are connected with the braking forceps to selectively clamp the braking discs. Due to the disc type brakes, the thermal stability and the water stability of the brakes are enhanced, the braking moment is increased, and the reliability and the safety of a vehicle are improved.
Description
Technical field
The utility model relates to a kind of automobile drive axle, relates in particular to a kind of employing hub reduction through-drive axle.
Background technology
Be equipped with the hub reduction through-drive axle in, the heavy type commercial vehicle is widely used in engineering construction and logistics transportation, traffic safety receives extensive concern.Wherein, the performance of brake system is to weigh the important indicator of safety performance.Present stage, in, employed hub reduction connects drive axle and adopts drum brake more in the heavy type commercial vehicle.The drum brake mechanism own characteristic has determined that under specific operation and environment, the deceleration and stopping performance of car load can descend to some extent, can't satisfy the requirement of safe driving.
The utility model content
The utility model is intended to propose a kind of hub reduction that is equipped with plate disc brake and connects drive axle.
The hub reduction of the utility model connects drive axle and comprises: wheel reduction gear, wheel hub, compressed air brake cylinder, plate disc brake; Said plate disc brake comprises brake clamp and brake disc; First side of wheel hub is connected with wheel reduction gear, and second side of wheel hub is connected with brake disc; Compressed air brake cylinder is connected in brake clamp, with clamping brake disc selectively.
Preferably, outer form is partially adopted in the installation of compressed air brake cylinder, and outer drift angle is 3 °-15 °.
Preferably, said wheel hub is equipped with unit bearing, and the internal diameter of said unit bearing is Φ 100mm-Φ 110mm.
Preferably, the reduction ratio of said wheel reduction gear is 3-4.
Owing to disposed plate disc brake, strengthen heat stability, water stability, the raising lock torque of drg, promote the reliability and the safety of vehicle.

The specific embodiment
Below, 1-3 is elaborated to the utility model in conjunction with Figure of description.
The wheel limit of the utility model connects drive axle and includes axle housing 5, connecting panel 7, track bar bracket 8, spring backing plate 4, spring bearer plate 3; Main reduction gear 10 is installed in the axle housing 5; Through being arranged in interaxle differential and the gear pair with parallel axes in the gap bridge case 9; The part imput power is passed to the main reduction gear 10 of through-drive axle, and another part power passes to the rear-axle drive bridge through thru shaft and output flange 6 simultaneously, and main reduction gear 10 is connected with planetary wheel reductor 1 through semiaxis; Wheel reduction gear 1 is fixed together with wheel hub 2; Wheel hub 2 is connected with brake disc 13, and brake clamp 12 is installed on the axle housing 5, and compressed air brake cylinder 11 is installed on the brake clamp 12.Brake disc 13 constitutes plate disc brake with brake clamp 12.
Outer form is partially adopted in the installation of compressed air brake cylinder 11, and outer drift angle A is 3 °-15 °, avoids compressed air brake cylinder 11 and bridge ontological existence movement interference in the braking procedure.Among Fig. 3, the angle of the horizontal axis of axis that outer drift angle A is a compressed air brake cylinder 11 and horizontal direction or axle housing 5.
The reduction ratio of wheel reduction gear 1 is 3-4.
Wheelspan 1800mm-1880mm, leaf spring width between centers 930mm-1040mm.
The axle housing 5 of the utility model adopts and dashes the weldering stage casing, and friction welding or electron beam welding are adopted in spindle nose and stage casing.
Owing to disposed plate disc brake, strengthen heat stability, water stability, the raising lock torque of drg, promote the reliability and the safety of vehicle.
Although illustrated and described the preferred embodiments of the present invention, it is contemplated that, those skilled in the art can be in the spirit of the utility model and scope design to the various modifications of the utility model.
