Description
Technical field
The utility model is related to road roller drive axle technical field more particularly to a kind of wet brakings of driving parking one
Tire hydraulic road roller drive axle.
Background technology
Currently, the braking system of tyre type full-hydraulic road roller drive axle includes mainly being located at drive axle main drive device and biography
" prime parking brake " between moving axis and " running brake " positioned at two side wheel side of drive axle, this two sets of braking system phases
It is mutually independent, generally use dry type braking.
But for the larger road roller of tonnage (general 25 tons or more) or under more complex, more severe working condition,
The reliability of exposed dry brake and safety also are difficult to meet the work requirements of road roller；And this design makes host
It is complicated, manufacturing cost is relatively also high.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of driving parking one proposed
The wet braking tire hydraulic road roller drive axle of body.
To achieve the goals above, the utility model uses following technical solution：
A kind of wet braking tire hydraulic road roller drive axle of driving parking one, including wet brake, driving
Bridge main reducing gear and drive axle cincture；Wet brake is mounted at the top of brake mounting board, the bottom peace of brake mounting board
Equipped with main reducing gear of drive axle, and the both ends of main reducing gear of drive axle are connected with drive axle cincture by shaft；
The middle part of wet brake is hollow structure, and inner bottom is equipped with the brake bush group of annular spread, institute
The top for stating brake bush group is equipped with parking braking piston close to one end of transmission shaft, the brake bush group
Top is equipped with service brake piston, and parking braking disc spring group, the parking system are equipped at the top of the parking braking piston
Parking braking oil pocket is equipped between piston and the inner wall of wet brake, between the service brake piston and wet brake
Equipped with service brake oil pocket.
The beneficial effects of the utility model are：Compared with prior art, the utility model has the following advantages：
1. driving, parking braking system are combined into one, keep drive axle structure compact, also drop the manufacturing cost of drive axle
It is low.
2. host can save a set of braking system, complete machine cost can be reduced；Structure is also simpler, and failure rate is lower.
3. using sealed Wet-type multi-disc Brake Design, the thermal stability and resistance tocrocking of braking are more excellent.
4. braking system wear is few and uniform, service life is long.
5. braking system is normally closed design, the automatic braking when host stops working is safe.
In conclusion the utility model has compact-sized, reliable, multiple functional, of low cost, the service life of braking
Feature long, safety is good.
Description of the drawings
Fig. 1 be the utility model proposes a kind of driving parking one wet braking tire hydraulic road roller drive axle
Positive structure diagram；
Fig. 2 be the utility model proposes a kind of driving parking one wet braking tire hydraulic road roller drive axle
Structural schematic diagram.
In figure：1 parking braking oil pocket, 2 service brake oil pockets, 3 parking braking disc spring groups, 4 parking braking pistons, 5 drivings
Brake piston, 6 brake bush groups, 7 brake mounting boards, 8 drive axle cinctures, 9 main reducing gear of drive axle.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of wet braking tire hydraulic road roller drive axle of driving parking one, including wet type system
Dynamic device, main reducing gear of drive axle 9 and drive axle cincture 8；Wet brake is mounted on 7 top of brake mounting board, brake peace
The bottom of loading board 7 is equipped with main reducing gear of drive axle 9, and the both ends of main reducing gear of drive axle 9 are connected with driving by shaft
Bridge cincture 8；
The middle part of wet brake is hollow structure, and inner bottom is equipped with the brake bush group 6 of annular spread, institute
The top for stating brake bush group 6 is equipped with parking braking piston 6, the brake bush group close to one end of transmission shaft
6 top is equipped with service brake piston 5, and the top of the parking braking piston 4 is equipped with parking braking disc spring group 3, described
Parking braking oil pocket 1, the service brake piston 5 and wet type are equipped between parking braking piston 4 and the inner wall of wet brake
Service brake oil pocket 2 is equipped between brake.
Operation principle：Parking braking state：When vehicle is not actuated or when vehicle stall or motor vehicle braking system failure
When --- parking braking oil pocket 1 is pressure release state, and the pressure that parking braking disc spring group 3 generates pushes parking braking piston 4 downwards
Fang Yundong compresses brake bush group 6, and drive axle is in parking braking state.
Parking braking releases state：When vehicle needs walking --- injection high pressure oil makes parking braking oil pocket 1 be in high pressure
State pushes parking braking piston 4 to move upward, and parking braking releases, while it is pressure release shape to keep service brake oil pocket 2
State, vehicle can walk.
Service brake state：When the vehicle of walking needs braking --- it is high pressure conditions to keep parking braking oil pocket 1, simultaneously
High pressure oil is injected, service brake oil pocket 2 is made to be in high pressure conditions, service brake piston 5 is pushed to move downwards, compresses brake
Friction plate group 6, vehicle is braked；
Emergency braking condition：When special circumstances need emergency braking --- 1 pressure release of parking braking oil pocket, while injecting height
Pressure oil makes service brake oil pocket 2 be in high pressure conditions, and parking braking piston 4 and service brake piston 5 move downwards, pressure
Tight brake bush group 6, vehicle is by emergency braking.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
