Abstract
The utility model relates to a tracked vehicle braking and driving mechanism, which mainly comprises a rear axle casing body, a central transmission mechanism, a steering clutch assembly, a brake assembly, a final transmission casing body, a driving axle, driving wheels, a driving axle gear, an intermediate axle gear, and an upper cover plate, etc.. The brake assembly adopts a floating type brake, and the final transmission device adopts a two-stage cylindrical gear transmission structure. The power is input by the central transmission, and through the deceleration and the torque increasing of the central transmission and the final transmission, the power output by the driving wheels can meet the driving force required by the walking of the tracked vehicle; the separation of the steering clutch can turn off the power of the driving wheels, and the driving wheels are stopped by the brake to realize the braking and the stopping of the tracked vehicle.
Description
(1) technical field:
The utility model belongs to the general vehicle field, relates to a kind of continuously tracked vehicle braking and driver train of being applicable to.
(2) background technology:
At present, the crawler-tread tractor that uses in China general vehicle field, crawler dozer and braking of other continuously tracked vehicles and driver train adopt single-ended tension drg usually and use a pair of gear-driven final transmission.Single-ended tension drg has the insecure shortcoming of braking, a pair of gear-driven final transmission, and transmitting ratio is also less, often can not satisfy the braking of continuously tracked vehicle and drive needs.Therefore continuously tracked vehicle braking and the driver train made from the way of improvement drg and final transmission transmitting ratio can satisfy the braking of continuously tracked vehicle and drive needs.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of braking and driveability good, the continuously tracked vehicle braking and the driver train of high efficiency.
The utility model can be achieved through the following technical solutions: continuously tracked vehicle braking and driver train, and mainly by rear axle housing body 1, central transmission device 2, steering clutch assembly 3, brake assembly 4, final transmission housing 5, axle drive shaft 6, drive wheel 7, driving shaft gear 9, upper cover plate 10 compositions such as grade.
In final transmission housing, between driving shaft gear 9 and the axle drive shaft 6 countershaft-gear 8 has been installed.The brake assembly 4 that is installed in the rear axle housing body 1 adopts the floating braking, has 4 arc friction linings on the brake collar at least, and the thick 6.5 ± 1mm of friction lining, inside face arc radius are 157.5 ± 1mm.The carriage of brake collar two ends fulcrum is fixed on below the back axle upper cover plate.
Central transmission device 2 is a pair of spira-bevel gearing, and steering clutch assembly 3 is made up of ten rotating plates, ten driven discs, driving drum, passive drum etc.Final transmission is the two-stage gear transmission, in the final transmission housing 5 two pairs of gear transmissions is arranged.Axle drive shaft 6 and drive wheel 7 bolt togethers are together.27 teeth are arranged on the drive wheel 7, and the reference diameter of the gear teeth is 741.5mm, and external diameter is 762mm, and the wheel facewidth is 70mm.
The utility model can reach following beneficial effect: power is imported by main gear, and the deceleration of process main gear and final transmission increases to be turned round, and the kinetic force of drive wheel output satisfies the propulsive effort of continuously tracked vehicle walking needs; Separate steering clutch, can cut off the power of drive wheel, drive wheel is stopped, realizing the continuously tracked vehicle stopping-down with drg.
(4) description of drawings:
Fig. 1 is braking of the utility model continuously tracked vehicle and driver train master TV structure figure.
Fig. 2 is braking of the utility model continuously tracked vehicle and driver train A-A section-drawing.
(5) specific embodiment:
With central transmission device 2, it is indoor to be installed in rear axle housing body 1 middle main gear, and steering clutch assembly 3, brake assembly 4 left-right symmetric respectively are installed in two reversal chambers of back axle, and upper cover plate 10 is installed in above the rear axle housing body 1; Axle drive shaft 6, countershaft-gear 8, driving shaft gear 9 are installed in the final transmission housing 5, and drive wheel 7 is installed on the axle drive shaft 6, and two final drive assemblies about being assembled into are installed in the two ends of rear axle housing body respectively, constitute whole braking and driver train.
During continuously tracked vehicle work, engine power to the central transmission device of braking with driver train, makes the drive wheel rotation through steering clutch, final driving device through change speed gear box again, drives the track rail assembly motion, thereby travels before and after making continuously tracked vehicle.Separate steering clutch when stopping and step on drg and can realize.
Claims (2)
