Abstract
Tractors Four-wheel brake control mainly by the transfer case type, small bevel gear shaft, brake pedal, sensors, large bevel gears, axle, brakes and other components. In transmission systems, the small bevel gears and shafts made of one small bevel gears, bevel gears meshing with the large momentum spread to the rear axle, rear axle axle inserted through the splined axle gears, brakes fitted around the rear axle axle , the transfer case driven gear and the small bevel gears meshing gear shaft, transfer case of bonding and separation is the electro-hydraulic control, transfer case output shaft by spline input shaft and front axle linked. About the same time the driver stepped on brake pedal, the sensor controlling the interface transfer case, front axle and rear axle connected to power, tractor rear wheel brakes, the front wheels while braking, to achieve four-wheel brakes. The structure of the advanced and reliable control.
Description
Technical field
The utility model belongs to the trac. field, relates to the automatically controlled four-wheel braking control of a kind of trac. pattern.
Background technology
At present, the high and medium power wheel-tire tractor of domestic production generally adopts the trailing wheel braking, promptly brakes two trailing wheels of trac. trac. is stopped, and this braking pattern is simple in structure, when trac. speed is not high, can satisfy brake request.But because braking force is subject to adhesive ability, when the trac. moving velocity surpassed 40km/h, the adhesive ability of trailing wheel was not enough to guarantee the braking force of trac., causes stopping distance too big.So when the trac. moving velocity surpassed 40km/h, the trailing wheel braking was difficult to guarantee the deceleration and stopping performance requirement.
The utility model content
The purpose of this utility model is to provide a kind of structure advanced person, uses the automatically controlled four-wheel braking control of trac. reliable, easy operation pattern, to improve the deceleration and stopping performance of large power wheel tractor.
The technical solution of the utility model is: the automatically controlled four-wheel braking control of trac. pattern, mainly comprise propons input shaft 1, auxiliary gear box output shaft 2, auxiliary gear box 3, auxiliary gear box driven gear 4, small coning gear shaft 5, bevel gear wheel 6, axle side gear 7, rear axle shaft 8, drg 9, brake pedal 10, trimming screw 11, sensor 12, it is characterized in that: bevel pinion and small coning gear shaft 5 are made of one, and with bevel gear wheel 6 engagement, rear axle shaft 8 inserts axle side gear 7 by spline, drg 9 is contained on the rear axle shaft 8, bevel pinion engagement on auxiliary gear box driven gear 4 and the small coning gear shaft 5, auxiliary gear box output shaft 2 is crossed spline and is connected with propons input shaft 1, trimming screw 11 is contained on the brake pedal 10, and trimming screw 11 heads withstand sensor 12.
The utility model can reach following beneficial effect, this device can not only guarantee the requirement of trac. deceleration and stopping performance, can also be directly by the brake pedal in the pilot control operator's compartment, thereby control joint that sensor realizes auxiliary gear box and separate, easy to use and reliable.
Description of drawings
Fig. 1 is the main TV structure scheme drawing of the automatically controlled four-wheel braking control of the utility model trac. pattern.
Fig. 2 is the pedal control scheme drawing of the automatically controlled four-wheel braking control of the utility model trac. pattern.
The specific embodiment
Shown in Fig. 1～2, the automatically controlled four-wheel braking control of trac. pattern mainly is made up of propons input shaft 1, auxiliary gear box output shaft 2, auxiliary gear box 3, auxiliary gear box driven gear 4, small coning gear shaft 5, bevel gear wheel 6, axle side gear 7, rear axle shaft 8, drg 9, brake pedal 10, trimming screw 11, sensor 12.In the transmission system, bevel pinion and small coning gear shaft 5 are made of one, by power being passed to back axle with bevel gear wheel 6 engagements, rear axle shaft 8 inserts axle side gear 7 by spline, drg 9 is contained on the rear axle shaft 8, bevel pinion engagement on auxiliary gear box driven gear 4 and the small coning gear shaft 5, the joint of auxiliary gear box 3 is electrohydraulic control with separating, and auxiliary gear box output shaft 2 is connected with propons input shaft 1 by spline, and trimming screw 11 is contained on the brake pedal 10, trimming screw 11 heads withstand sensor 12, be screwed into or the trimming screw 11 of back-outing, when making its head withstand sensor 12, sensor 12 disconnects, step on brake pedal 10, sensor 12 is connected.
The automatically controlled four-wheel braking control of trac. pattern principle of work: when chaufeur was stepped on left and right sides brake pedal 10 simultaneously, two sensors 12 were connected, and auxiliary gear box 3 engages, the power of propons links to each other with back axle, trac. trailing wheel glancing impact, front-wheel is braked simultaneously, thereby realizes four-wheel braking.
