Abstract
The invention provides a pneumatic speed changer brake, which comprises a shaft, a spring, a gear, a spline shaft, a steel sheet, a friction plate, a piston, a cylinder and an air path. The piston which does reciprocating motion along the shaft and the spline shaft sleeved on the shaft are arranged in the cylinder; the spring is arranged between the piston and the spline shaft; the steel sheet and the friction plate are arranged on the two sides of the spline shaft; the steel sheet is connected with the gear through the spline shaft; the friction plate is connected with the spline shaft through a spline; and the air path is arranged at the end of the shaft and connected with the piston and the cylinder. When the speed changer is shifted up, the brake can quickly reduce the rotation speed of the shaft and related parts of the speed changer, shorten the synchronization time and improve the gear shift performance.
Description
Technical field
The present invention relates to the speed changer braking device, relate in particular to a kind of pneumatic speed changer brake.
Background technique
Along with fast development of national economy, people are more and more higher to the requirement of car steering travelling comfort.As the speed changer of automobile power-transmission system vitals, driving comfortability mainly refers to the quality of shifting gears, i.e. smooth gear shifting, power interruption time weak point.
Domestic research to speed changer brake at present is at the early-stage, and the speed changer brake that is contained in power taking window place is still blank.External speed changer brake complex structure, the maintenance and installation trouble, versatility is very poor.Therefore, necessary a kind of break can be given one of speed changer and related component thereof when speed changer upgrades, carry out braking deceleration, need synchronous part synchronous fast when making gearshift, thereby shorten power interruption time, make the driver feel smooth gear shifting.
Summary of the invention
In order to solve existing technical problem in the background technique, the present invention proposes a kind of pneumatic speed changer brake, when speed changer upgrades, this break can be to one of speed changer and related component thereof, carry out rotating speed and reduce rapidly, shorten lock in time, improve the gearshift performance.
Technical solution of the present invention is: the present invention is a kind of pneumatic speed changer brake, and its special way is: described break comprises axle, spring, gear, splined shaft, steel disc, friction plate, piston, cylinder and gas circuit; Be provided with an edge axle pistons reciprocating in the described cylinder, and be nested in the splined shaft on the axle, be provided with spring between described piston and the splined shaft; Described steel disc and friction plate are arranged on the both sides of splined shaft, and described steel disc is connected by spline with gear; Described friction plate is connected the end that described gas circuit is arranged on axle by spline with splined shaft, be connected with piston and cylinder.
Above-mentioned steel disc and friction plate are a plurality of.
Above-mentioned break includes housing, and described splined shaft is fixing with housing.
The contacted place of above-mentioned splined shaft and housing is provided with straight pin.
Be provided with ball bearing between said gear and the splined shaft.
Advantage of the present invention is:
1, break of the present invention can carry out braking deceleration to one of speed changer and related component thereof when speed changer upgrades.Need synchronous part synchronous fast when this just can make gearshift, thereby shorten power interruption time, reduced the power loss of motor, eliminated the pause and transition in rhythm or melody sense when automobile upgrades to a certain extent.
2, break is installed in power taking window place, and braking inertia is less relatively.Simultaneously flexible for installation, also need not the speed changer body is changed, also can conveniently utilize the car load source of the gas.Because to engine power utilization ratio height, so this break can obviously improve the power character and the fuel economy of automobile.
3, break of the present invention adopts pneumatic mode, conveniently utilizes the car load source of the gas, and is simple in structure, easy to connect, also saves the energy simultaneously.Because it is nearer from the car load source of the gas, pipeline is apart from weak point, and piston stroke is short, so braking response time and lag time are all very short.
4, brake application of the present invention is extensive, can be installed in MT, and the power taking window place of AMT of medium and heavy vehicles such as commercial car and passenger vehicle as required.

Embodiment
The pneumatic speed changer brake that the present invention proposes comprises axle 1, pad 2, bearing 3, baffle plate 4, spring 5, gear 6, ball bearing 7, straight pin 8, housing 9, splined shaft 10, steel disc 11, friction plate 12, piston 13, cylinder 14, gas circuit 15.Piston 13 is along axle 1 to-and-fro motion in cylinder 14, and splined shaft 10 is nested on the axle 1, and spring (5) is arranged between piston 13 and the splined shaft 10; Gas circuit 15 is arranged on the end of axle 1, is connected with piston 13 and cylinder 14.
Steel disc 11, friction plate 12 all are most, and number can be adjusted installation as required, to adapt to different brake requests.Steel disc 11 and friction plate 12 are adaptive mutually; , steel disc 11 and friction plate 12 are divided into two groups, are separately positioned on the both sides of splined shaft 10.The break that the present invention proposes is installed in force taking window of speed variator mouth place, and the gear 6 and the transmission gear of break are intermeshing.Because the gear 6 of break is installed in the speed changer outside, therefore design is flexible relatively, and its braking inertia is also less relatively.
Concrete working procedure is: when speed changer need upgrade, earlier speed changer is plucked neutral gear.Controller is given the solenoid valve electrical signal then, solenoid valve is opened, pressurized air enters in the axle 1 by solenoid valve, enter in the cylinder 14 by the gas circuit on the axle 1 15, gas circuit 15 is circular groove or other pipeline configurations, and cylinder 14 promotes piston 13 to the right, and piston 13 overcomes the spring force of spring 5, and pressing friction sheet 12 and steel disc 11, steel disc 11 and friction plate 12 are alternately; Wherein friction plate 12 links together by spline and splined shaft 10.Splined shaft 10 is fixed together with brake casing 9.Steel disc 11 and gear 6 link together by spline.Friction plate 12 and steel disc 11 be owing to the impacting force of piston 13 produces frictional force, so just can partly carry out braking deceleration to the speed changer that meshes together with spragging gear 6.When reaching the deceleration requirement, solenoid valve outage commutation, gases communicate with atmosphere in the cylinder 14.At this moment, spring 5 promotes piston 13 left, just gas in the jar can be discharged, and eliminates braking force simultaneously.
The design of two straight pins 8 in cylinder body 14 left and right sides can make the relative position between each parts obtain better fixing, and has guaranteed the good assembling of break.Be provided with ball bearing 7 between gear 6 and the splined shaft 10, can make spragging gear 6 bear certain axial force, avoid it to move axially.
Break of the present invention adopts pneumatic mode, conveniently utilizes the car load source of the gas, and is simple in structure, easy to connect, also saves the energy simultaneously.Because it is nearer from the car load source of the gas, pipeline is apart from weak point, and piston stroke is short, so braking response time and lag time are all very short.
