Abstract
The invention provides a novel electric vehicle disc brake installation structure which belongs to the technical field of machinery, and solves the problems of complicacy and trouble in installation of an existing motor vehicle disc brake installation structure. The novel electric vehicle disc brake installation structure is arranged on a hub, and comprises a brake disc, a chuck and an installation support which are sleeved on an axle; the brake disc and the chuck are fixedly connected through a brake disc bolt; a shaft sleeve is sleeved on the axle and both ends of the shaft sleeve are respectively fixed on the brake disc and the hub; the outer diameter of the chuck is a little smaller than the inner diameter of the hub and an oblique slot is arranged on the chuck; an expansion block is inlaid in the oblique slot; and the expansion block is fixedly connected with the brake disc and the chuck through expansion bolts. The electric vehicle disc brake installation structure has the advantages that: the combination of structural parts is simple; the overall installation is convenient and easy; the expansion force is uniform; and the use is safe and firm.
Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of battery-driven car, the disc brake mounting structure on particularly a kind of battery-driven car.
Background technology
Existing battery-driven car is most of, and what install is drum brake mechanism, and Along with people's is to the continuous demand of vehicle performance, and battery-driven car develops to such an extent that vehicle body is heavier gradually, and the speed of a motor vehicle is faster, like this drum brake mechanism satisfied not car brakeing required.Hydraulic brake is compared with drum-type, mainly contains following advantage: lock torque is big, braking is steady; Thermal diffusivity is good; But automatic compensation after the brake plate wearing and tearing; Installation and maintenance are convenient.Hydraulic brake is reequiped or disposed to therefore a large amount of battery-driven cars.The disc brake installing mechanism mainly is made up of brake disc, chuck, the parts such as piece, brake disc bolt, adapter plate, axle sleeve, transition bracket that expand on the battery-driven car at present; First fixedly brake disc and chuck during installation; Again adapter plate, the piece that expands, brake disc bolt are fitted together; Then take advantage of a situation and pack in the vehicle hub; 3 the brake disc bolts of evenly screwing, at this moment 3 bloated pieces simultaneously along chuck outside inclined-planes outwards (axially) move sleeve mechanism swelling (rely on chuck, the static friction force that produces between piece, the wheel hub three that expands brake disc is fixed on the wheel hub) in wheel nave, guarantee the face runout≤0.2mm of brake disc and wheel shaft after the installation.But this mounting structure part unitized construction is complicated; The comparison difficulty because 3 bloated pieces are packed into simultaneously, conformability is bad when evenly screwing again, and the face runout of brake disc and wheel shaft is bigger after causing installing; Even sleeve mechanism has been fixed not on wheel hub; Give to install smoothly and bring many troubles, and 3 piece ratios that independently expand are easier to become flexible, cause installing the normal vehicle operation that has influence on not in place.
Summary of the invention
The objective of the invention is to have the problems referred to above to existing technology, it is simple to have proposed a kind of constructional delails combination, and integral installation is convenient simple and easy, the novel electric vehicle disc brake mounting structure that tension force is even and safety is firm.
The object of the invention can be realized through following technical proposal: a kind of novel electric vehicle disc brake mounting structure; Be installed on the wheel hub; Comprise the brake disc, chuck and the mounting bracket that are socketed on the wheel shaft; Described brake disc and chuck are fixed together through the brake disc bolt, be socketed with on the described wheel shaft axle sleeve and axle sleeve two ends be separately fixed on the brake disc with wheel hub on, it is characterized in that; Described chuck external diameter is slightly less than the wheel hub internal diameter and on chuck, offers skewed slot, is inlaid with expanding block and expanding block in the described skewed slot and is connected through cinch bolt and brake disc and chuck.
Earlier brake disc, chuck and expanding block bolt together are in the same place during installation; Wherein 2 brake disc bolts are fastening with brake disc and chuck; 1 cinch bolt connects brake disc and bloated piece (piece that expands is embedded in the chuck skewed slot); Then entire mechanism is taken advantage of a situation and pack in the wheel hub, through tightening cinch bolt pulling expanding block expanding block is strutted chuck, and then make the even swelling of chuck in wheel hub.This mounting structure part makes up simple, and integral installation is convenient simple and easy, and tension force is even and safety is firm.
In above-mentioned novel electric vehicle disc brake mounting structure, the angle angle of the sidewall that described skewed slot two is relative is 10 °～20 °.As preferred version, the angle angle of two relative sidewalls is 15 ° of the bests.
In above-mentioned novel electric vehicle disc brake mounting structure, size and skewed slot size that the sectional area of described expanding block is trapezoidal and expanding block are complementary.
In above-mentioned novel electric vehicle disc brake mounting structure, also offer two bolts hole and described two bolts hole and skewed slot on the described chuck and be evenly distributed on the chuck.
In above-mentioned novel electric vehicle disc brake mounting structure, described chuck adopts aluminum alloy materials to process.Chuck adopts the ZL111 aluminum alloy materials, carries out T6 heat treatment, thus mechanical characteristicss such as the tensile strength of raising product and hardness.
In above-mentioned novel electric vehicle disc brake mounting structure, pad is installed between described brake disc and the mounting bracket and described pad is socketed on the wheel shaft.Pad mainly is used for adjusting the relative spacing between mounting bracket and the brake disc, thereby prevents to occur after mounting bracket is installed on the wheel shaft problem of axial offset.
Compared with prior art, the present invention has the following advantages:
Earlier brake disc, chuck and expanding block bolt together are in the same place when 1, installing; Wherein 2 brake disc bolts are fastening with brake disc and chuck; 1 cinch bolt connects brake disc and bloated piece (piece that expands is embedded in the chuck skewed slot); Then entire mechanism is taken advantage of a situation and pack in the wheel hub, through tightening cinch bolt pulling expanding block expanding block is strutted chuck, and then make the even swelling of chuck in wheel hub.This mounting structure part makes up simple, and integral installation is convenient simple and easy, and tension force is even and safety is firm.
2, chuck adopts the ZL111 aluminum alloy materials, carries out T6 heat treatment, thus mechanical characteristicss such as the tensile strength of raising product and hardness.
