As further improvement of the utility model, the main increment of described rear-axle casing is also provided with the flanged structure for connecting Parking Brake.
As further improvement of the utility model, described Parking Brake connecting bottom board comprises the outer ring that is provided with unthreaded hole and the inner ring that is provided with tapped bore, described outer ring and rear-axle casing are fixedly linked, and described inner ring and Parking Brake are fixedly linked, by fastening as a whole to Parking Brake and rear-axle casing.
As further improvement of the utility model, described flange of cardinal tooth is the hollow tube-shape structure that its lower end is sheathed on main pinion outside, and the inside, lower end of flange of cardinal tooth is provided with female splines, and the main tooth male splines on flange of cardinal tooth female splines and main pinion is intermeshing.
The beneficial effects of the utility model are:
1, the utility model is by applying resistive torque to drive axle torque input end, realize braking during standstill to car load, actv. has solved the problem that in the time of idle narrow and small after wheel limit complex structure and change speed gear box and part-time case, undercapacity Parking Brake is difficult to layout.
2, this braking during standstill mode, can amplify lock torque, realizes the output of larger lock torque by less braking force or less brake specification.
3, reduce braking during standstill apparatus quantity (traditional Parking Brake is each one of left and right wheels end), simplified assembly structure; Alleviate deadweight, compare traditional Parking Brake arrangement, weight reduction approximately more than 3%, improved fuel economy.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
For improving car load crossing ability, design and develop the rigid drive axle with central inflation/deflation structure wheel limit.This structure needs larger space, wheel limit, so that be difficult to arrange Parking Brake on wheel limit.For solving an above-mentioned difficult problem, newly design a kind of arrangement of Parking Brake, i.e. the drive axle assembly of input end parking.
The structure of the rigid drive axle of the utility model input end parking as shown in Figure 1, this rigid drive axle is arranged at the torque input end of drive axle assembly, comprises rear-axle casing 1, Parking Brake connecting bottom board 2, Parking Brake 3, flange of cardinal tooth 4, brake wheel 5 and transmission shaft 6.Wherein, rear-axle casing 1 is fixedly connected with by Parking Brake connecting bottom board 2 with Parking Brake 3, the lower end of flange of cardinal tooth 4 is sheathed on main pinion 12 outsides, and the inside, lower end of flange of cardinal tooth 4 is provided with female splines 13, and flange of cardinal tooth 4 female spliness 13 are intermeshing with the male splines on main pinion 12.The flange end of flange of cardinal tooth 4 is fixedly connected with the brake wheel 5 of transmission shaft 6 and Parking Brake 3, by fastening as a whole to transmission shaft 6, brake wheel 5, flange of cardinal tooth 4.
This drive axle assembly, using the rear-axle casing 1 newly designed and developed as body, increases flanged structure 7 at the main increment of former rear-axle casing, and as shown in Figure 2, the rear axle housing structure of increase flanged structure 7 of the present utility model as shown in Figure 3 for the structure of former rear-axle casing.
Because limited by Parking Brake connection dimension, Parking Brake connecting bottom board 2 structures of the present utility model are preferably structure shown in Fig. 4, and its scheme of installation as shown in Figure 5.This Parking Brake connecting bottom board 2 comprises the outer ring 8 that is provided with 5 unthreaded holes 10 and the inner ring 9 that is provided with 4 tapped bore 11, outer ring 8 is fixedly linked with rear-axle casing 1, inner ring 9 is fixedly linked with Parking Brake 3, by fastening as a whole to Parking Brake 3 and rear-axle casing 1, as stator.
For brake wheel and parking device actv. processed cooperating, flange of cardinal tooth 4 structures of the present utility model are preferably structure shown in Fig. 6, and its scheme of installation as shown in Figure 7.Flange of cardinal tooth 4 is sheathed on the hollow tube-shape structure of main pinion outside for its lower end, and flange of cardinal tooth 4 female spliness coordinate with main tooth male splines.Flange of cardinal tooth 4 flange ends are connected with the brake wheel 5 of Parking Brake, by bolt, and by fastening as a whole to the brake wheel of transmission shaft 6, Parking Brake 5, flange of cardinal tooth 4, as rotor, transmitting torque.
When vehicle parking, chaufeur, by a series of elements, applies application force to Parking Brake, and Parking Brake (stator) applies resistance by friction lining to brake wheel (rotor), prevents that brake wheel from rotating.Brake wheel is connected with driving gear flange, transmission shaft, thereby stops the rotation of driving gear flange (main tooth), transmission shaft.Main tooth is fixed, and drive wheel cannot move forwards or backwards simultaneously.Like this, whole system just can be carried out braking during standstill to car load reliably.
