Technical field
The invention belongs to field of mechanical technique, relate to a kind of battery-driven car, the disc brake installation structure particularly on a kind of battery-driven car.
Background technology
What existing battery-driven car major part was installed is drum brake mechanism, and along with people are to the continuous demand of vehicle performance, battery-driven car develops vehicle body is heavier gradually, and the speed of a motor vehicle is faster, and such drum brake mechanism can not meet car brakeing and require that.Hydraulic brake, compared with drum-type, mainly contains following advantage: lock torque is large, braking is steady; Thermal diffusivity is good; Can auto-compensation after brake plate wearing and tearing; Installation and maintenance are convenient.Therefore a large amount of battery-driven car is reequiped or is configured with hydraulic brake.On current battery-driven car, disc brake installing mechanism is primarily of brake disc, chuck, expansion block, brake disc bolt, adapter plate, axle sleeve, the parts compositions such as transition bracket, brake disc and chuck is first fixed during installation, again by adapter plate, expansion block, brake disc bolt fits together, then take advantage of a situation and load in vehicle hub, evenly screw 3 brake disc bolts, at this moment 3 expansion blocks move along the outer inclined-plane of chuck outside (axis) simultaneously and sleeve mechanism swelling (are relied on chuck in wheel nave, expansion block, the static friction force produced between wheel hub three makes brake disc be fixed on wheel hub), ensure the face runout≤0.2mm of brake disc and wheel shaft after installing.But this mounting structure part combination complex structure, because 3 expansion blocks load more difficult simultaneously, when evenly screwing, conformability is bad again, cause the face runout installing rear brake disc and wheel shaft larger, even sleeve mechanism is not fixed on wheel hub, give to install smoothly and bring many troubles, and 3 independently expansion block ratio be easier to loosen, cause installing not in placely having influence on normal vehicle operation.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose the combination of a kind of constructional delails simple, integral installation facilitates simple and easy, tension force Novel electric vehicle disc brake installation structure evenly and securely.
Object of the present invention realizes by following technical proposal: a kind of Novel electric vehicle disc brake installation structure, be arranged on wheel hub, comprise the brake disc be socketed on wheel shaft, chuck and mounting bracket, described brake disc and chuck are fixed together by brake disc bolt, described wheel shaft is socketed with axle sleeve and axle sleeve two ends are separately fixed on brake disc and on wheel hub, it is characterized in that, described chuck external diameter is slightly less than wheel hub internal diameter and offers skewed slot on chuck, expanding block is inlaid with and expanding block is connected by cinch bolt and brake disc and chuck in described skewed slot.
First brake disc, chuck and expanding block are bolted together during installation, wherein 2 brake disc bolts by brake disc and chuck fastening, 1 cinch bolt connects brake disc and expansion block (expansion block is embedded in chuck skewed slot), then whole mechanism is taken advantage of a situation and load in wheel hub, pull expanding block that chuck is strutted by expanding block by tightening cinch bolt, and then make the even swelling of chuck in wheel hub.This mounting structure part combination is simple, and integral installation facilitates simple and easy, and tension force evenly and securely.
In above-mentioned Novel electric vehicle disc brake installation structure, the angle angle of the sidewall that described skewed slot two is relative is 10 ° ~ 20 °.Preferably, the angle angle of two relative sidewalls is 15 ° of the bests.
In above-mentioned Novel electric vehicle disc brake installation structure, the sectional area of described expanding block is trapezoidal and the size of expanding block and skewed slot size match.
In above-mentioned Novel electric vehicle disc brake installation structure, described chuck also offers two bolts hole and described two bolts hole and skewed slot are evenly distributed on chuck.
In above-mentioned Novel electric vehicle disc brake installation structure, described chuck adopts aluminum alloy materials to make.Chuck adopts ZL111 aluminum alloy materials, carries out T6 heat treatment, thus the mechanical characteristics such as the tensile strength of raising product and hardness.
In above-mentioned Novel electric vehicle disc brake installation structure, between described brake disc and mounting bracket, pad is installed and described pad is socketed on wheel shaft.Pad is mainly used to adjust the relative spacing between mounting bracket and brake disc, thus prevents mounting bracket to be arranged on the problem occurring axial offset after on wheel shaft.
Compared with prior art, the present invention has the following advantages:
First brake disc, chuck and expanding block are bolted together when 1, installing, wherein 2 brake disc bolts by brake disc and chuck fastening, 1 cinch bolt connects brake disc and expansion block (expansion block is embedded in chuck skewed slot), then whole mechanism is taken advantage of a situation and load in wheel hub, pull expanding block that chuck is strutted by expanding block by tightening cinch bolt, and then make the even swelling of chuck in wheel hub.This mounting structure part combination is simple, and integral installation facilitates simple and easy, and tension force evenly and securely.
2, chuck adopts ZL111 aluminum alloy materials, carries out T6 heat treatment, thus the mechanical characteristics such as the tensile strength of raising product and hardness.
