Description
Technical field
The present invention relates to disk brake, specially a kind of disc brake with fixed caliper with cooling duct.
Background technique
Rotating element in disk brake friction pair is the rosette to be worked with end face, referred to as brake disc.Friction member
Part clamps brake disc from two sides and generates braking.Then there are many structure types for fixing element, generally can be by disk brake point
For two class of caliper disc and complete-disc.
Spot-type disc brake can be divided by the structural shape of caliper determines caliper disc and two kinds of floating caliper type disc, determines caliper disc system
For dynamic device in braking, brake block clamps brake disc from two sides respectively, and the braking of brake disc is realized under the action of the two frictional force,
Therefore disc brake with fixed caliper a large amount of heat will be generated under the action of frictional force in braking process, if the heat cannot and
When distribute, the abrasion of brake block will be caused, the failure of brake will be caused when serious, influence the driving safety of vehicle.
Summary of the invention
It, cannot to solve heat in braking process the invention is intended to provide a kind of disc brake with fixed caliper with cooling duct
The problem of distributing caused brake wear or even misfunctioning of brake in time.
The disc brake with fixed caliper with cooling duct in this programme, including caliper and brake disc, caliper are fixed on
In external vehicle bridge, caliper across offering oil inlet and flow channel for liquids on the brake disc two sides, caliper, oil inlet and
Flow channel for liquids communicates, and is axially and symmetrically set centered on brake disc on flow channel for liquids there are two piston, piston is set towards brake disc side
There is brake block, cooling duct is also provided on piston, cooling duct two sides are communicated with flow channel for liquids, and the side of cooling duct is also
Equipped with the check valve for preventing adverse current.
The principle of this programme is: when needing to brake brake disc, brake fluid enters liquid from the oil inlet of caliper
Body runner pushes the piston of brake disc two sides to move to brake disc direction into the brake fluid in flow channel for liquids, and piston exists
The brake block to link together with piston is driven to move jointly to brake disc direction while movement, until the braking of two sides
Block and brake disc are close together, and while brake fluid pushes piston motion, the brake fluid of part will also enter in piston
Cooling duct, in cooling duct under the action of check valve, brake fluid has the side of check valve to enter from cooling duct, leads to from cooling
The other side in road is returned in flow channel for liquids, when brake block is close to brake disc, under the action of the two frictional force, and brake disc
Speed slow down and be decreased until stopping slowly, in the process, brake block will generate a large amount of heat under the action of frictional force, this
The major part of a little heats will be transmitted at the piston to connect between brake block, at this time process of the brake fluid in piston in flowing
It is middle the heat for being transmitted to piston timely to be taken away.
The beneficial effect of this programme is: by the way that cooling duct is arranged in piston, the flowing of brake fluid will in cooling duct
Brake block is timely and effectively transmitted to the heat at piston to take away, so that brake block be made to be able to maintain in braking process suitable
Temperature, while higher pressure will be generated from the brake fluid of carrying heat that cooling duct comes out, and then make brake block and system
The fitting of Moving plate is even closer, and braking effect is more preferable, therefore the heat that can take away brake in time of the brake using this programme
Amount, prevents the abrasion of brake block, to ensure that the stability of brake operation performance.
Further, it in order to separate brake block can with brake disc in time after completing braking, is set between piston and caliper
There is tension spring, tension spring one end offsets with caliper, and the tension spring other end offsets with piston.
Further, piston is equipped with protrusion towards brake disc side, and protrusion can offset under the action of the tension spring with caliper,
Upon completion of the braking, tension spring drives brake block to separate with brake disc, until the protrusion of piston offsets with caliper end face.
Further, in order to which caliper is fixed, at the same stress caused by removing caliper in process concentrate,
Phenomena such as burr, caliper are fixed with external vehicle bridge by welding, and the end of caliper, which is additionally provided with, prevents stress concentration
Circular arc chamfering.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
