Abstract
The utility model relates to a hydraulic braking device for a small articulated steering type tractor, which belongs to the braking device of the tractor, particularly the hydraulic braking device of the small articulated steering type tractor. The hydraulic braking device of the small articulated steering type tractor is mainly composed of a brake pedal, a brake master cylinder, a front brake cylinder, a gear box, a brake wheel, a brake band, and a hydraulic brake disk. The brake pedal is connected with the tappet of the brake master cylinder; one output path of the brake master cylinder is communicated with the hydraulic brake disk of the brake rear wheel; the other path is communicated with the front brake cylinder, and the tappet of the front brake cylinder is connected with the brake band through a transmission member.
Description
The utility model relates to a kind of brake equipment of trac., the hydraulic brake system of particularly small-sized articulated steering formula transportation type trac..
At present, the brake equipment of small-sized articulated steering trac. all adopts the mechanical type post brake device, and its braking force is lower than 25 kilometers/hour transportation type trac. for speed per hour can be satisfied substantially.But surpass 25 kilometers/hour transportation type trac. for speed per hour, then braking force is less, can not satisfy safety arrestment.
The purpose of this utility model provides a kind of brake equipment of small-sized articulated steering trac., and it adopts the mode of hydraulic braking, simultaneously front and back wheel is braked, braking force is bigger, can satisfy the safety arrestment requirement that speed per hour surpasses 25 kilometers/hour trac., simple in structure, exceed the increase cost.
The technical solution of the utility model is: it mainly is made up of brake pedal, master brake cylinder, preceding brake cylinder, change speed gear box, brake wheel, brake collar and hydraulic braking dish, brake pedal connects the tappet of master brake cylinder, master brake cylinder has the two-way output oil pipe, one the tunnel passes to the hydraulic braking dish of braking rear-wheel, another road passes to preceding brake cylinder, the tappet of preceding brake cylinder connects brake collar by Transmission, brake collar is contained in the outer rim of brake wheel, and brake wheel is connected with secondary variable shaft in the gear box of tractor.
Below, according to the specific embodiment of the present utility model that Figure of description provides, its structure is done further carefully to state.
Fig. 1 is a structural representation of the present utility model.
Referring to each figure, this brake equipment mainly is made up of brake pedal 7, master brake cylinder 8, preceding brake cylinder 5, change speed gear box 1, brake wheel 3, brake collar 2 and hydraulic braking dish 11, brake pedal 7 connects the tappet of master brake cylinder 8, master brake cylinder 8 has the two-way output oil pipe, one the tunnel passes to the hydraulic braking dish 11 of braking rear-wheel, another road passes to preceding brake cylinder 5, the tappet of preceding brake cylinder 5 connects brake collar 2 by Transmission, brake collar 2 is contained in the outer rim of brake wheel 3, and brake wheel 3 is connected with secondary variable shaft in the gear box of tractor 1.Master brake cylinder 8 is after being communicated with T-pipe joint 12 by back oil pipe 9, to lead to hydraulic braking dish 11 by rear brake line 13 again; Before brake cylinder 5 with being in transmission connection of brake collar 2 be, be connected by its tappet and connect on the fork 14, connect fork 14 and connect an eccentric wheel 4 again, eccentric wheel 4 is connected in the open end of brake collar 2 at last.When the needs glancing impact, depress brake pedal 7, the tappet of master brake cylinder 8 moves and begins mutual work, with oil pipe 6 before brake solution in the lubricating cup 10 that master brake cylinder 8 links to each other is divided into two-way and is imported into respectively and back oil pipe 9 for the front and back braking; The brake solution that enters back oil pipe 9 is through T-pipe joint 12, rear brake line 13, promote hydraulic braking dish 11, make the piston and the jib motion of its brake cylinder, brake shoe brake cheek is pushed up to brake hub realize back braking (structure of this part is identical with conventional automobile, so represent no longer in the drawings to reach carefully to state); Simultaneously, brake cylinder 5 before brake solution in the preceding oil pipe 6 promotes, the piston and the tappet of preceding brake cylinder 5 move, connecing that promotion links to each other with its tappet pitches 14, connect fork 14 and again its motion is passed to the eccentric wheel 4 that is attached thereto, eccentric wheel 4 rotates and compresses the open end of brake collar 2, thereby holds brake wheel 3 tightly, brake wheel 3 links to each other with secondary variable shaft in the gear box of tractor 1, reaches the purpose of braking front-wheel by the braking change speed gear box
From technique scheme of the present utility model as seen: this device has adopted hydraulic brake system small-sized articulated steering trac., and simultaneously front and back wheel is braked, braking force is improved a lot, thereby can satisfy the safety arrestment requirement that speed per hour surpasses 25 kilometers/hour trac. fully, in addition, this device simple in structure made and installed and all be easier to, and can not increase cost therefrom too much.
