Abstract
The utility model relates to a composite hydraulic brake. The problem that the domestic existing hydraulic brake is unable to meet the requirement of the brake performance for a load carrier whose total mass is 7 tons to 10 tons and a passenger car whose total length is 8 meters to 10 meters is solved by the mechanism. The mechanism is characterized in that an initial vacuum pressure booster assembly is arranged between a vacuum booster and a right and a left front brake assemblies. A final vacuum pressure booster assembly is arranged between the vacuum booster and a right and a left rear brake assemblies, and the assemblies are all connected through a hydraulic pipeline. Through testing on a passenger car whose total length is 8 meters, the brake performance meets the relevant legislation, and pedals are felt light and convenient when the utility model is used. In addition, the brake response is sensitive.
Description
The utility model relates to a kind of automobile braking mechanism, exactly is a kind of composite hydraulic brake equipment.
Present domestic goods carrying vehicle and passenger vehicle mainly adopt the double circuit hydraulic braking arrangement of two kinds of patterns.A kind of is the device that adopts vacuum intensifier, and another kind is the device that adopts vacuum booster.
The main weak point of above-mentioned two kinds of devices is, it is the requirement of 7～10 tons autotruck and the total length passenger vehicle that is 8～10 meters to deceleration and stopping performance that its lock torque all can't satisfy total mass.Above-mentioned in addition two kinds of devices in use all have stretcher to feel deficiencies such as heavy, brake response hysteresis.
Chinese patent CN2209077Y discloses a kind of pressure-balance type full automatic car emergency brake device, this device is main by linking in the hysteresis open and close type shutoff valve of vehicle brake pedal, master brake cylinder arm, the spring energy-storage chamber is formed, the moment that causes brake failure when the motor vehicle braking system cataphoretic failure, the work of shutoff valve automatic command elastic energy accumulation chamber, realize emergency brake, guarantee vehicle driving safety.Chinese patent CN2229390Y discloses a kind of self-propelled vehicle safety shut-down for another example, on this brake gear, support (2) is arranged, and is installed on driving lever (7) on the support and is installed on lock pin (1) control on the support (2); By Das Gaspedal (12) compressing throttle depression bar (13), bent axle (11) is rotated, drive push rod (15), promote to crank arm driving lever (16), stir key (1), starting driving lever (7) is depressed pedal of clutch (8) and brake pedal (10), finishes brake.Chinese patent CN2234385Y discloses a kind of automobile emergency scotch for another example, and it is by the drive link (1) and operating handle (2), reel cage (4), cam holder (3) and the arc scotch formations such as (5) that are installed on car bottom and the crossbeam.Use this device, be aided with original service brake again, shortened braking distance greatly, braking effect is splendid.
The utility model aim to provide a kind of can satisfy total mass be 7 tons～10 tons goods carrying vehicle and total length be 8 meters～10 meters passenger vehicle to the deceleration and stopping performance requirement, operate light, the composite hydraulic brake equipment of brake response sensitivity.
The technical solution that realizes above-mentioned aim is such, a kind of composite hydraulic brake equipment, form by operation mechanism of pedal, storage liquid kettle, vacuum booster band tandem brake master cylinder assembly, vacuum pump, vacuum cylinder, vacuum intensifier assembly and brake assembly, it is characterized in that:
Between vacuum booster band tandem brake master cylinder assembly and left and right front brake assembly, be provided with an initial vacuum blwr assembly; Between vacuum booster band tandem brake master cylinder assembly and left and right rear brake assembly, be provided with a final vacuum and increase the device assembly; All connect between the above-mentioned assembly by hydraulic tubing; The vacuum line of vacuum cylinder one end is divided into three branch roads, is connected with vacuum booster band tandem brake master cylinder assembly, initial vacuum blwr assembly and final vacuum blwr assembly respectively.
The utlity model has the advantage of three aspects:
One, this brake equipment is united use owing to having adopted with vacuum booster and vacuum intensifier, brake pedal force amplified through two-stage can producing enough big lock torque, is that 7 meters～10 meters passenger vehicle is to the requirement of deceleration and stopping performance to satisfy 6 tons～10 tons tins of goods carrying vehicles and total length.
Two, this brake equipment is through being to test on 8 meters the passenger vehicle at total length, and deceleration and stopping performance satisfies relevant laws and regulations requirement, and pedal sense is light when using, the brake response sensitivity.
Three, the utility model reasonable in design is arranged compactness, and good manufacturability is easy for installation.
Description of drawings,
Fig. 1 is the utility model structural representation.
Below by embodiment, in conjunction with the accompanying drawings the utility model is further described.
As seen from Figure 1, this composite hydraulic brake equipment comprises brake pedal mechanism 7, storage liquid kettle 1, vacuum booster band tandem brake master cylinder assembly 2, vacuum pump 4, vacuum cylinder 5, vacuum intensifier assembly and brake assembly.
Vacuum booster band tandem brake master cylinder assembly 2 connects with initial vacuum blwr assembly 9 by a hydraulic tubing 12, and initial vacuum blwr assembly 9 is communicated with right front brake assembly 3, left front brake assembly 8 again; Connect with final vacuum blwr assembly 10 by another hydraulic tubing 12, final vacuum blwr assembly 10 is communicated with right back brake assembly 6, left back brake assembly 11 again.Vacuum pump 4 is communicated with vacuum cylinder 5 by vacuum line 13, and the other end vacuum line 13 of vacuum cylinder 5 is divided into three branch roads, is connected with vacuum booster band tandem brake master cylinder assembly 2, initial vacuum blwr assembly 9 and final vacuum blwr assembly respectively.
In the use, the control effort that chaufeur applies pedal (being treadle effort) is delivered to vacuum booster 2 by brake treadle mechanism 7, promoting the series connection total pump piston after vacuum booster 2 one-levels are amplified makes the braking liquid in the master cylinder be transported in the auxiliary cylinders of forward and backward vacuum intensifier 9,10 respectively with higher pressure, be transported to the brake wheel cylinder of left and right front brake assembly 8,3 and left and right rear brake assembly 11,6 behind the two stage supercharging of forward and backward vacuum intensifier 9,10 more respectively, the piston of brake wheel cylinder promotes brake shoe brake cheek generation lock torque and makes automobile brake.
