Said service braking system comprise be arranged in the drawbar device, the one of which end is fitted with braking tappet returning device; The braking tappet that the other end and master brake cylinder are oppositely arranged; Wherein, master brake cylinder be fixed in the braking drawbar and be arranged on wheel braking drum in brake cylinder between oil circuit be communicated with, the wheel braking drum is fixed on the wheel; When the braking tappet obtains above-mentioned difference force of inertia; Its may command master brake cylinder is communicated with oil circuit between the brake cylinder, and the wheel braking drum is fixed on the wheel, realizes braking with this.
Further be, said master brake cylinder into and out of oil pipe respectively with being connected of brake cylinder into and out of oil pipe.
As the further improvement of the utility model, said master brake cylinder comprises the master brake cylinder piston that is oppositely arranged with braking tappet one end, and this master brake cylinder piston moves with the oil circuit between control brake master cylinder and the brake cylinder under the effect of braking drawbar.
Said brake cylinder is arranged in the wheel braking drum; Brake shoe for drum brake one end in its brake cylinder piston and the wheel braking drum is oppositely arranged, and the other end of brake shoe for drum brake is provided with the brake shoe brake cheek returning device, therefore; When the brake cylinder piston promotes brake shoe for drum brake, service brake; Otherwise, brake off.
For the drawbar device is connected with the drawbar hook better, said drawbar device is connected with the drawbar hook through the drawbar coupling link.
It is good that said braking tappet returning device adopts pull back spring.
It is good that said brake shoe brake cheek returning device adopts pull back spring.
The mobile crushing station that the utility model provides has fully used equipment tractor truck glancing impact with four types of chassis; The difference force of inertia that between itself and four types of chassis, produces; These four types of chassis are the power resources of this difference force of inertia as service braking system, thereby have not only effectively avoided the equipment tractor truck to receive four types of chassis impulsive forces forward when emergency situation needs emergency braking running into, and have improved the deceleration and stopping performance of equipment tractor truck greatly; Park the reliability height during service brake; Also can avoid the equipment tractor truck to be damaged, improve the service life of equipment tractor truck, make this mobile crushing workstation can be widely used in the frequent industry that needs the resettlement operation for a long time neatly because of receiving this impulsive force; It is simple in structure, and braking is reliable.

The specific embodiment
For purpose, technical scheme and the beneficial effect that is expressly understood the utility model more, below in conjunction with accompanying drawing the utility model is done further explanation, but the protection domain of the utility model is not limited in following examples.
Shown in Fig. 1 to 3; A kind of mobile crushing station with service braking system is with four types of chassis; These four types of chassis comprise that front end passes through that drawbar hook 2 is connected with equipment tractor truck 1, rear end and propons 4 bonded assembly drawbar devices 3; Back axle 5 and frame assembly 6, the difference force of inertia that is provided with in this drawbar device 3 to produce between equipment tractor truck 1 glancing impact and the four types of chassis is the service braking system of power; Said service braking system comprise be arranged in the drawbar device 3, the one of which end is fitted with braking tappet returning device 8; The braking tappet 10 that the other end and master brake cylinder 12 are oppositely arranged; Wherein, Master brake cylinder 12 be fixed in the braking drawbar 9 and be arranged on wheel braking drum 16 in brake cylinder 14 between oil circuit be communicated with, wheel braking drum 16 is fixed on the wheel; Said master brake cylinder 12 into and out of oil pipe 13 respectively with being connected of brake cylinder 14 into and out of oil pipe 19; Said master brake cylinder 12 comprises the master brake cylinder piston 11 that is oppositely arranged with braking tappet 10 1 ends, and this master brake cylinder piston 11 moves under the effect of braking drawbar 9 with the oil circuit between control brake master cylinder 12 and the brake cylinder 14; Said brake cylinder 14 is arranged in the wheel braking drum 16, and its brake cylinder piston 15 is oppositely arranged with wheel braking drum 16 interior brake shoe for drum brake 17 1 ends, and the other end of brake shoe for drum brake 17 is provided with brake shoe brake cheek returning device 18; Said drawbar device 3 is connected with drawbar hook 2 through drawbar coupling link 7; Said braking tappet returning device 8 is a pull back spring; Said brake shoe brake cheek returning device 18 is a pull back spring.
Need to prove, wheel braking drum all is installed on each wheel on four types of chassis, be provided with brake cylinder in each wheel braking drum, being communicated with into and out of oil pipe and master brake cylinder of each brake cylinder into and out of oil pipe.
Its principle of work is: in equipment tractor truck 1 traction mobile crushing workstation driving process, step on brake; The antagonistic force of the force of inertia forward that the mobile crushing workstation produces promotes braking tappet 10, backs down the master brake cylinder valve thereby promote master brake cylinder piston 11, and brake circuit is opened; Through flowing to the brake cylinder 14 that is loaded in the drum brake mechanism into and out of oil pipe 13; Brake cylinder 14 oil circuits are connected, brake cylinder piston 15 under the oil pressure effect to two outside displacements, promote brake shoe for drum brake 17 to wheel braking drum 16 near; Until fitting car brakeing fully; After the vehicle parks, force of inertia disappears, and braking tappet 10 is retraction under the effect of braking tappet returning device 8, and the power that acts on the master brake cylinder piston 11 disappears, and braking fluid is back to master brake cylinder 12; Because brake cylinder 14 no pressure outputs, brake cylinder piston 15 is retraction under brake shoe return spring 18 effects, and brake shoe for drum brake 17 is thrown off wheel braking drum 16, the driving brake off.
