Description
Technical field
The utility model relates to technical field of automobile components, definite a kind of automobile starter, the more precisely brush assembly of automobile starter of saying.
Background technology
Brush assembly is one of vitals in motor.Brush assembly on existing automobile starter includes brush carrier, brush box is installed on brush carrier, in brush box, be provided with brush and brush spring, brush box front end is brush outlet, brush box rear end is provided with closure plate, brush is slidably installed in brush box, brush is inner for stretching out the brush outlet of brush box the conducting end contacting with commutator, brush spring one end is pressed on brush, the brush spring other end is against on closure plate, on brush sidewall, connect brush pigtail, brush box sidewall is provided with the open slot slipping into for brush pigtail, the opening of open slot exports towards brush, wherein the brush of brush assembly consists of two positive brushes and two negative pole brushes, four brushes are uniformly distributed, two positive brush positioned opposite, two negative pole brush positioned opposite.There is following defect in existing brush assembly: 1) brush is loss parts, the place that brush contacts with commutator is constantly subject to the friction of commutator, brush weares and teares gradually, brush weares and teares and shortens under the promotion of brush spring, but while may wear to a certain degree, brush pigtail directly contacts with commutator, commutator is caused to damage, when serious, will produce spark, cause accident, the slip of brush only relies on the through hole in brush box, in the slightly high situation of temperature, the slippage of brush in brush box has some setbacks, easily there is catching phenomenon, make brush unreliable with contacting of commutator, cause machine operation unstable, 2) brush is when being used early stage, for the power of avoiding brush to be pressed on commutator overweight, the setting of the starting force of brush spring can not be excessive, and brush only relies under the top pressure effect of brush spring after wearing and tearing, slippage forward, under the effect of spring force, brush front end keeps being fitted on circulator and keeps electrically contacting with commutator, but the wearing and tearing along with commutator, spring force diminishes, the pressure on top surface that later stage brush top is pressed on commutator diminishes, it is too large that the initial spring force of brush spring can not be set, later stage, exist the contact force of brush and commutator too small, exist and be electrically connected to insecure defect, and being damaged too early, scraps by brush, cause the wasting of resources, 3) starter positive brush is all that brush is distinguished to electric wire extends, take into account the function of lead-out wire, the diameter of lead-out wire is subject to brushing the impact of pigtail, setting is not only unfavorable for maintenance and changes like this, and the most important thing is, the extended line that two brushes are distinguished merges as lead-out wire, the sectional area of lead-out wire is two times that single brush is distinguished sectional area, according to resistivity formula R=p 1/S, in unit length, the resistance value R of lead-out wire
1, the resistance value R distinguishing with single brush
2between pass be R
2=2R
1, and the electric current of the lead-out wire of flowing through, mean allocation to two brush distinguishes, i.e. work I
1=2I
2, according to Joule law Q=I
2rt can learn, at electric current and conductor material constant in the situation that, and in same time, two times of distinguishing for brush of the heat that the lead-out wire of unit length produces, i.e. Q
l=2Q
2, brush body and brush distinguish and be sealed in starter inside, and lead-out wire is arranged at outside starter, be connected, and in order to prevent short circuit, lead-out wire outer setting has sheath with external circuit, when external control circuit breaks down or when manual operation is made a fault, starter can long-time energising, and lead-out wire caloric value increases sharply, being wrapped in sheath outside lead-out wire etc. is very likely ignited, cause lighting naked light, cause vehicle spontaneous combustion, and cause security incident.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of brush of avoiding to cross wearing and tearing, and brush moves reliable and stable, safe and reliable automobile starter brush assembly.
