Description

The integrated type electric vehicle brake

One, technical field

The utility model relates to a kind of drg of battery-driven car braking usefulness.

Two, background technology

Battery-driven car is a kind of emerging vehicle, and its load-carrying, F-Zero and car body strength are between bicycle and the motor bike.The main flow of battery-driven car drg is that front and back wheel all adopts drum brake mechanism basically at present, and its braking effect is unsatisfactory.Because the drum brake mechanism heat dispersion is poor, a large amount of heats that produce in braking procedure very easily cause the brake facing temperature build-up, friction coefficient descends, and causes " heat fade ", and promptly brake efficiency descends, the insensitivity variation, and in braking, produce noise owing to temperature is too high; And in a single day rainwater enters drum brake mechanism, and friction coefficient is descended, and causes " water fade ", and water is difficult for out, and restorative poor, brake efficiency descends, thereby has reduced traveling security.The disc brake with motor bike that also has directly is loaded on the battery-driven car, and the disc brake brake is hurriedly impacted bigger to the battery-driven car car body, and the long-term use car body very easily produces fracture by fatigue.Existing plate disc brake is applied on automobile or the motor bike, the split-type structural of lower pump body in its pump housing (comprising main pump housing, branch pump case) employing, and mechanical strength is relatively poor.The trend of battery-driven car industry development is to substitute drum brake with disc type brake.

Three, utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and the integrated type electric vehicle brake that a kind of mechanical strength height, insensitivity are good, structure is simplified is provided.

The purpose of this utility model realizes by following technical solution: a kind of integrated type electric vehicle brake, described drg are plate disc brake, and it comprises main pump assembly, oil pipe assembly, oil-feed bolt, divides pump assembly, brake disc; The main pump housing of described main pump assembly and divide the branch pump case of pump assembly to be one-piece construction, on the top of the branch pump case of described minute pump assembly, and above the inside and outside friction lining of minute pump assembly, locate to be equipped with the friction lining guide rod.

After adopting the utility model,, improved the mechanical strength of drg because main pump housing and branch pump case are one-piece construction; After having adopted plate disc brake, its brake disc is exposed in the air and high speed rotating, radiating effect is good, and brake disc is followed wheel and is rotated together, can throw away water or mud, and " water is restorative " is better, deceleration and stopping performance is stable, improved traveling security greatly, long service life and at the glancing impact noiselessness, it is also very convenient to change inside and outside friction lining.Therefore, the soften of the existing bicycle brake of this brake has the stability of motorcycle brake again, has improved the quality and the performance of drg.

Five, the specific embodiment

With reference to accompanying drawing as can be known, the utility model integrated type electric vehicle brake, described drg are plate disc brake, and it comprises main pump assembly 1, oil pipe assembly 2, oil-feed bolt 3 (and seal ring 4), divides pump assembly 5, brake disc 7; The main pump housing 1a of described main pump assembly 1 and divide the branch pump case 1b of pump assembly 5 to be one-piece construction, on the top of the branch pump case 1b of described minute pump assembly 5, and above inside and outside friction lining 11b, the 10b of minute pump assembly 5, locate to be equipped with friction lining guide rod 8b.Wherein, the material of brake disc 7 is 1Cr13, and it is between inside and outside friction lining 11b, the 10b of branch pump assembly 5, and is contained on the electric bicycle wheel shaft by brake disc bolt 8; Divide pump assembly 5 rack-mount, easy for installation by two stands hold-down bolt 6; The material of main pump housing, branch pump case is cast aluminium alloy ZL101A.

As Fig. 2 to shown in Figure 4, described main pump assembly 1 by main pump housing 1a, pull back spring 2a, oil cup cover screw 3a, lubricating cup pad 4a, oil cup cap 5a, preceding leather cup 6a, O shape circle 7a, plain cushion 8a, back-up ring 9a, dust cap 10a, piston mandril 11a, main pump piston 12a, partly cover screw 13a, handle pin 14a, collar 15a, rivet 16a, line formula switch 17a, handle 18a and form.Wherein main pump housing 1a adopts one-piece construction, the compact conformation light weight, and the mechanical strength height, exquisite appearance, processing is easy for installation easily, long service life; Described handle 18a joins by piston mandril 11a and main pump piston 12a, has increased the stationarity of main pump piston motion; The handle configuration design is held and is felt more comfortable according to the human engineering data; If release handle, handle and main pump piston self-return under the effect of pull back spring makes the oil circuit release.

As Fig. 5, shown in Figure 6, described minute pump assembly 5 (claiming brake clamp again) form by a minute pump case 1b (have oil circuit, be similar to oil cylinder), wheelcylinder piston 2b, rectangular seal 3b, air bleeder nipple 4b, air bleeder nipple dust boot 5b, O-ring seals 6b, sealing of hole plug 7b, friction lining guide rod 8b, friction lining spring 9b, outside friction disc 10b, internal friction sheet 11b, collar 12b.Wherein collar 12b is enclosed within the outer end of friction lining guide rod 8b; The top of described minute pump case 1b, and sealing of hole plug 7b and O-ring seals 6b are housed, easily seal not easy oil leakage, also be convenient to install inside and outside friction lining after pulling down the sealing of hole plug at internal friction sheet 11b place; Branch pump case 1b (being braking clamp body) adopts one-piece construction, light weight, and exquisite appearance, the mechanical strength height, heat radiation is good, long service life; The outer end of described friction lining spring 9b is contained on the friction lining guide rod 8b, is beneficial to the fixing of friction lining spring.

Principle of work of the present utility model is: when the needs drag, with holding tight handle (joystick), utilize the lever principle handle to promote piston mandril and make main pump piston forward (being left shown in Figure 2) motion, make hydraulic pressure rising in the main pump assembly, hydraulic pressure promotes wheelcylinder piston by the oil cylinder that the oil pipe assembly is delivered to branch pump assembly (brake clamp), wheelcylinder piston promotes inside and outside friction lining, by inside and outside friction lining brake disc is clamped, produce braking force and make battery-driven car stop to travel, deceleration and stopping performance is reliable, stable.After release handle, handle and main pump piston self-return under the effect of pull back spring makes the oil circuit release.After the oil circuit release, the wheelcylinder piston return, inside and outside friction lining separates with brake disc under the effect of friction lining spring, guarantees normally driving.In use, it is very convenient to change inside and outside friction lining, only need back out the friction lining guide rod, takes out inside and outside friction lining, loads onto new inside and outside friction lining, tightens the friction lining guide rod and gets final product.
