Abstract
The utility model discloses a kind of drive axle caliper, belong to engineering machinery field.Which overcoming engineering truck in the prior art, because braking is frequent, braking moment is big, causes the defects of caliper heating is serious, and sealing ring failure oil leak situation increases.Including outer caliper, piston, friction plate, interior caliper, the outer caliper is fixedly connected with interior caliper, and outer caliper is provided with oil inlet and outlet and ventilative mouth, and the outer caliper and interior caliper are respectively provided with three piston cylinders, a piston, piston outer end connection friction plate are provided with each piston cylinder.Braking moment is significantly increased on the basis of braking radius is not increased in the utility model, lifts braking ability, meets the braking requirement of especially large-tonnage engineering truck.
Description
Technical field
The utility model belongs to a kind of engineering machinery accessory, specifically, more particularly to a kind of drive axle caliper.
Background technology
The caliper disc caliper of existing engineering truck, widely used single-piston or double-piston.During braking, in brake fluid
Or in the presence of hydraulic oil, both sides piston moves in the piston cylinder of caliper, friction plate is promoted, so that friction plate and braking
Disk compresses, and produces braking moment.
Engineering truck such as wheel loader, braking is frequent, braking moment is big, causes caliper heating serious, sealing ring mistake
Effect oil leak situation increases, and reduces the braking ability of caliper；Especially current large-tonnage loading machine, the application of fork installation are more general
And, it is necessary to bigger braking moment, such as increase the quantity of caliper, it is necessary to more installing spaces, and by cost increase etc.
Limitation.
Utility model content
The utility model purpose is to provide a kind of drive axle caliper, with overcome in the prior art engineering truck due to system
The defects of dynamic frequent, braking moment is big, causes caliper heating seriously, and sealing ring failure oil leak situation increases.
The utility model is realized using following technical scheme：
A kind of drive axle caliper, including outer caliper, piston, friction plate, interior caliper, the outer caliper and interior caliper are consolidated
Fixed connection, outer caliper are provided with oil inlet and outlet and ventilative mouth, and the outer caliper and interior caliper are respectively provided with three piston cylinders, each living
A piston, piston outer end connection friction plate are provided with plug cylinder.
It is connected together between the piston cylinder.
The friction plate is arranged on outer caliper and internal side of making up tong by bearing pin.
Two seal grooves are provided with the piston cylinder, two rectangular seals are installed in the seal groove.
Compared with prior art, the beneficial effects of the utility model are：
(1) three pairs of pistons are provided with caliper provided by the utility model, on the basis of braking radius is not increased, significantly
Increase braking moment, lift braking ability, meet the braking requirement of especially large-tonnage engineering truck；
(2) single piston of the present utility model is provided with two rectangular seals, and the sealing of caliper greatly improved, solution
Determine the failure problems of current caliper sealing ring oil leak, also acted as dust-proof effect, totally improve vehicle brakes
Performance.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of drive axle caliper, including outer caliper 1, piston 2, rectangular seal 3, friction
Piece 4, interior caliper 5, connecting bolt 6, ventilative mouth 7, bearing pin 8, outer caliper 1 and interior caliper 5 are linked together by connecting bolt 6,
Outer caliper 1 and interior caliper 5 are respectively provided with three piston cylinders, and each piston cylinder is connected together in outer caliper 1 and interior caliper 5.
The piston cylinder is designed with two seal grooves, and two rectangular seals 3 are provided with the seal groove, and it is made
Be improve caliper sealing, while close to friction plate 4 rectangular seal 3, also act as dust-proof effect.
A piston 2, the outer end of piston 2 connection friction plate 4 are provided with each piston cylinder, described two friction plates 4 pass through pin
Axle 8 is arranged on outer caliper 1 and the inner side of interior caliper 5, is positioned over brake disc both sides.
Outer caliper 1 is provided with oil inlet and outlet and ventilative mouth 7, and oil inlet and outlet is used for hydraulic oil or brake fluid flows into and discharge
Piston cylinder, ventilative mouth 7 are used for being vented.
When vehicle is braked, hydraulic oil or brake fluid are injected to piston cylinder by the oil inlet and outlet of outer caliper 1, in piston cylinder
Hydraulic oil or brake fluid are acted on both sides piston 2, and piston 2 promotes the friction plate 4 of both sides to be slided by bearing pin 8, compress system
Moving plate, so as to produce braking moment, the braking to vehicle is realized, when releasing braking, hydraulic oil or brake fluid pass through outer caliper 1
Oil inlet and outlet outflow, piston 2 moves backward, and then the take-off the brake disk of friction plate 4.
