Abstract
A wet type brake gear used in the front driving axle of the tractor is mainly composed of an active hub, a driving friction disc, a driven friction disc, a disk spring, piston, a brake oil cylinder shell and an O-ring. The driving hub is connected with differential shells of the front driving axle of the tractor via the spline; the shell of the braking oil cylinder is fixed in the driving bearing of the front driving axle; multipairs of the driving friction discs and the driven friction discs are installed between the driving hub and the shell of the braking oil cylinder; the piston is installed inside the braking oil cylinder; an end surface of the piston presses firmly onto the piece disc on braking; the disk spring fits over the piston end; the end face sticks on the shell of the braking oil cylinder. On braking, the hydraulic oil presses firmly the driving friction disc and the driven friction disc via the piston to brake the driving hub; on pressure relieving, the driving friction disc separates from the driven friction disc, so that the driving hub rotates. The brake is controlled by the hydraulic or by the braking pump in the cabin, which is compact in structure and reliable in handling.
Description
(1) technical field
The utility model belongs to the trac. field, relates to a kind of Wet Type Brake Gear using for Farm Tractor Front Drive Axle.
(2) background technology
Present domestic large power wheel tractor front driving axle is band brake not generally, so this class trac. is difficult to satisfy its deceleration and stopping performance when moving velocity is too high.In order to remedy this deficiency, be necessary in this class trac. front driving axle, drg to be set, make it have good deceleration and stopping performance, to satisfy the brake request of large power wheel tractor.
(3) summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, use Wet Type Brake Gear using for Farm Tractor Front Drive Axle reliable, easy operation, to satisfy the brake request of large power wheel tractor.
The technical solution of the utility model is: Wet Type Brake Gear using for Farm Tractor Front Drive Axle mainly comprises initiatively hub, active friction plate, driven disc, disk spring, piston, brake cylinder housing, it is characterized in that: initiatively hub links to each other with trac. front driving axle differential casing by spline, and the brake cylinder housing is fixed on the front driving axle awl driving support seat; Initiatively be equipped with many between hub and the brake cylinder housing to active friction plate and driven disc; Piston is contained in the brake cylinder housing, and piston end surface compresses driven disc at glancing impact, and disk spring is enclosed within piston tail, and end face is attached on the brake cylinder housing.
The utility model can reach following beneficial effect: because brake gear adopts multi-disc wet friction sheet, oad is little, can be arranged in trac. front driving axle middle part easily; Drg adopts hydraulic actuated, and by the control of the brake pump in the operator's compartment, compact conformation is handled reliably good braking effect.
(4) description of drawings
Fig. 1 is the main TV structure cutaway view of the utility model front driving axle with the wet braking apparatus.
(5) specific embodiment
As shown in Figure 1, front driving axle mainly is made up of active hub 5, active friction plate 6, driven disc 7, disk spring 3, piston 4, brake cylinder housing 1, O shape circle 2 etc. with the wet braking apparatus.Initiatively hub 5 links to each other with front driving axle differential casing 9 by spline, and brake cylinder housing 1 is fixed on the front driving axle awl driving support seat 8; Initiatively be equipped with many between hub 5 and the brake cylinder housing 1 to active friction plate 6 and driven disc 7.Piston 4 is contained in the brake cylinder housing 1, and piston 4 end faces compress driven disc 7 at glancing impact, and disk spring 3 is enclosed within piston 4 afterbodys, and end face is attached on the brake cylinder housing 1.
The drg principle of work: the plunger shaft that glancing impact, hydraulic oil enter drg overcomes the returning place force of disk spring 3, and promoting piston 4 will manyly compress active friction plate 6 and driven disc 7, braking differential casing 9, thus brake bevel gear wheel 10.During separation, the hydraulic oil in the plunger shaft is by the control oil channel off-load, and at this moment disk spring 3 retracts piston 4.Operator on the tractor can produce braking oil pressure by step on the brake pump pedal in operator's compartment.
