Technical field
The present invention relates to a kind of mechanical disc brake device, particularly a kind of disc brake mounting board of battery-driven car and improved connection structure of wheel hub motor shaft of being applied to.
Background technology
Driving brake, is grown with each passing hour to disc brake type by drum-type, rim type, and disc brake generally is installed on most self-propelled vehiclees with its superior braking effect, and brake this safety, life-saving device, there is no the right of failure.Though the disc brake effect is good, but complex structure, installation requirement is higher, disc brake is to lean on the pulling force of brake cable rub and clamp disc by the brake facing in clamp, produce braking effect, therefore requiring between the brake facing of disc and disc brake has enough good parallelism, and disc and disc brake assembly are mounted in wheel hub and rotating shaft thereof, that is to say that the mounting structure between disc brake assembly and rotating shaft directly affects the braking effect of disc brake.existing disc brake when mounted, first the adapter plate with disc brake is installed in rotating shaft, then pad is put pad until the brake lining of disc is in the center position of two brake facings between adapter plate and hub shell, disc and adapter plate are in the state of opposing parallel, prevent the adapter plate axial offset with nut locking again, this mounting structure practical operation is got up very loaded down with trivial details, need to adjust by a plurality of pad stacks and just can reach requirement, there is manufacturing errors in two end faces of pad self, a plurality of pad stacks can increase accumulated error again, setting accuracy is low, the brake lining that can not guarantee disc is the center position that is in two brake facings, moreover, pad is subject to the impact of external factor and deformation occurs, and makes mounting structure become unstable, the easy positioning of adapter plate.The appearance of above-mentioned situation just makes the braking effect of disc brake greatly descend, and has brought potential safety hazard to the cyclist.
Summary of the invention
Problem to be solved by this invention just is to provide the connection structure of a kind of disc brake mounting board and wheel hub motor shaft, and the adjustment problem when the solution disc brake is connected with wheel hub motor shaft makes the easier for installation of disc brake, and braking quality is stable, reliable.
for reaching above-mentioned purpose, the present invention adopts following technical scheme: the connection structure of a kind of disc brake mounting board and wheel hub motor shaft, comprise disc brake assembly, wheel hub motor shaft reaches for the adapter plate that disc brake assembly is arranged on wheel hub motor shaft, described adapter plate is provided with the mounting hole that passes for wheel hub motor shaft, it is characterized in that: described wheel hub motor shaft is provided with registration device, described adapter plate is locked on registration device by the bonding mechanism that is located on mounting hole, described registration device comprises axle sleeve and the jam nut that is socketed on wheel hub motor shaft, described axle sleeve is locked on wheel hub motor shaft by jam nut, the left side of axle sleeve and wheel hub side lean, bonding mechanism comprises the inner hole sleeve of being located in mounting hole and is used for the inner hole sleeve double team is locked at snap ring on axle sleeve, under locking state, the both ends of the surface of described axle sleeve are stretched out respectively the left side of inner hole sleeve and the right side of snap ring.
Further, described wheel hub motor shaft is provided with a shaft shoulder section, and described axle sleeve inner ring surface is provided with the positioning step that offsets with described shaft shoulder section.
Further, described inner hole sleeve left end is connected with mounting hole inner hole surface close-fitting, inner hole sleeve right-hand member and the active clamping of described snap ring.
Preferably, the left part of described inner hole sleeve is provided with a riveting mouth, inner hole sleeve by the tight-lipped close expanded joint of riveting on the inner hole surface of mounting hole.
Preferably, described inner hole sleeve right part is provided with the outstanding annular edge eaves of an outward radial, and the inner ring surface of described snap ring is provided with and the mutual clamping annular groove of described annular edge eaves.
Further, described snap ring is the annulus with opening, and described opening is provided with two tight lock parts that are bolted, and described snap ring is drawn close the double team locking that realizes inner hole sleeve relatively by two tight lock parts.Tight lock part not only is used for the locking of snap ring, can also connect by connection structure other function accessories of disc brake, simplifies the disc brake self structure.
Further, described snap ring is made by nylon.The nylon snap ring has certain elastic recovery effect in distortion, if adapter plate has slight positioning, can carry out by the elastic reaction of snap ring the oneself and adjust; Nylon snap ring and shaft room can produce relatively moving between larger friction force restriction adapter plate and core retainer plate, good stability when chucking.
Beneficial effect of the present invention: the present invention has changed the connection structure of traditional disc brake and wheel hub motor shaft, has solved the axial offset problem of adapter plate on wheel hub motor shaft; Disc brake no longer needs the pad adjustment after the brake tension, as long as by bonding mechanism, adapter plate is locked on registration device, after brake was loosened, disc brake need not to adjust again, and disc has been in the center position of two brake facings, and is easy for installation, laborsaving; In the disc brake use procedure, bonding mechanism can play good fixation, even mild asymmetry appears in adapter plate, bonding mechanism also can carry out the oneself to be adjusted it is resetted, and makes the braking quality of disc brake more stable, reliable.
